Agenda

• ACA-Py Updates:

  • Fix (3450) multi-tenant/single wallet should avoid for an issue in 1.2.0 is to be released Any Day Now – 1.2.1. Plus another fix (3458) and a new upgrade test (3457) that caught these.

    • Release Candidate at least today.

  • Issue being fixed that is occurring periodically in the test harness with ACA-Py hanging on startup.

    • Issue seems to be with pushing standard in/standard out through a pipe.

  • Ready to move on removing AIP 1.0 from ACA-Py to ACA-Py Plugins (various PRs in both repos).

  • Proposal to enable major version updates via dependabot PRs – for example this PR (3455) updates multiple important dependencies.

    • More warnings and we’ll have to make a call on ignoring some vs. investing in enabling them.

  • Plan for extending the OID4VC plugin to support Batch Issuance – looking for interested parties to collaborate on this.

    • Related: OID4VCI draft 15 is out – we should update the plugin to that draft – perhaps in conjunction with Batch support

  • Progress on a VCDM 2.0 PR 3436 – please review. Side effect – “issuance_date” required in VCDM 1.0, “valid_from” optional in VCDM 2.0

    • We’re doing processing (sorting) on valid_from date – but ordered by received date

  • Creation of a Universal Registrar plugin (PR 1376)

  • Progress on did:webvh plugin to support DIDs and AnonCreds objects.

• Part 2: Status List Plugin – overview and demo.

• The Cheqd.io Plugin – overview and demo.

• Not Covered:

  • did:webvh Resources: “Attested Resources” and Linked Resources in did:webvh for AnonCreds Objects and More

    • did:webvh resources <did>/path/to/file, where the HTTP path defaults to match the DID location (minus .well-known) – any content

    • AttestedResources – the identifier for the resources (the DID URL) commits its content, and there is a proof from the DID Controller.

      • The hash of the resource is hashed to produce the file name: <did>/path/to/<hash>.<ext>

      • The resource contains a proof of the resource

    • AnonCreds – Schema, CredDef, RevRegDef

      • RevRegEntries are trickier, because the holder doesn’t know the Identifier for the Entry it wants to use. Needs to get a list of the entries and then retrieve the one of interest.

• Open Discussion
